| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

Nonvolatiles of commercial lime and grapefruit oils separated by high-speed countercurrent chromatography.[Pubmed:16536603]
J Agric Food Chem. 2006 Mar 22;54(6):2242-52.
The nonvolatile fractions of cold-pressed peel oils of Key and Persian lime as well as grapefruit were separated by high-speed countercurrent chromatography (HS-CCC). In addition to the isolation of the main coumarins, psoralens and polymethoxyflavones, a number of minor constituents were enriched and successfully characterized by GC-MS and HPLC-UV. 5,7,8-Trimethoxycoumarin and the cyclical acetals of oxypeucedanin hydrate with citral were determined as new nonvolatile trace constituents of lime oils and confirmed by NMR spectroscopy. The citral oxypeucedaninyl acetals were found particularly in Key lime oil type A, which as a result of the juice-oil contact, is exposed to acidic conditions during industrial processing. Some of the confirmed minor constituents, such as pabulenol, isooxypeucedanin, and oxypeucedanin methanolate in lime as well as auraptenol in grapefruit, may have been generated by hydrolysis-sensitive precursors during CCC separation or their respective industrial processing techniques.
[Studies on the chemical constituents of Rutaceae++ plants. LXVI. The chemical constituents of Toddalia asiatica (L.) Lam. (T. aculeata Pers.). (1). Chemical constituents of the root bark].[Pubmed:1783985]
Yakugaku Zasshi. 1991 Jul;111(7):365-75.
Chemical constituents of the root bark of Toddalia asiatica (L.) Lam. (T. aculeata Pers.), Rutaceae, were examined. In addition to twelve known coumarins [toddaculin (2), coumurrayin (5), toddanone (6), 8-(3,3-dimethylallyl)-6,7-dimethoxycoumarin (7), isopimpinellin (8), 6-(3-chloro-2-hydroxy-3-methylbutyl)-5,7-dimethoxycoumarin (9), 6-formyllimettin (10), 5,7,8-Trimethoxycoumarin (12), toddasin (13), (+)-toddanol (14), 6-(2-hydroxy-3-methoxy-3-methylbutyl)-5,7-dimethoxycoumarin (18), and toddalolactone (21)] five new coumarins [toddalenol (17), toddalosin (19), 5-methoxysuberenon (23), toddalenone (24), and 8-formyllimettin (25)] were isolated. Furthermore seven known benzo[c]phenanthridine alkaloids [des-N-methylchelerythrine (4), oxychelerythrine (15), arnottianamide (16), oxyavicine (22), avicine (30), chelerythrine (31), and chelerythrine-psi-cyanide (34)] and four known quinoline alkaloids [N-methylflindersine (11), 4-methoxy-1-methyl-2-quinolone (20), skimmianine (35), integriquinolone (36)], one known triterpenoid [beta-amyrin (3)], and four unknown components [unknown I-IV (26)-(29)] were isolated.
